COTTON CHUTE.

Application filed April 1?, 1922.

To all whomit may concern:

Be it known that I, WILLIAM L. IIANCUCIL a citizen of the United States, residing at Dallas. in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Cotton Chutes, of which the following is a. specification.

My invention is an improved adjustable chute for delivering seed cotton from the gin feeder to either the huller roll'box Or to the ginning roll box, of a huller gin, as may be desired. My object is to make the ad justment as simple, easy and accurate as may be.

In the drawings Figure 1 is an end elevation partly in section of the general assembly, showing the gin feeder and the upper part of a gin, with the chute interposed between them, showing the chute in two positions, one in dotted lines;

Figure is a front elevation, broken, of the chute, on an enlarged scale;

Figure 3 is a. cross-section on line 33 of Figure 2; and

Figure 4 is an end view of the chute, showing the parts in a different position.

My chute is especially designed for use between a feeder or feeder-cleaner and a huller gin, i. e. a gin which has two feed openings, one opening to the ginning roll box, as in a plain gin and the other opening to an outer or huller roll box, where seed cotton is given a preliminary treatment before it is carried to the ginning ribs.

In Figure 1, I have indicated the main parts of such a huller gin, A. 1 is the opening to the ginning roll box; 2, the ginning ribs and, 3, the ginning saws; 4; is the opening to the huller roll box and 5 the huller ribs. The gin herein partially illustrated is a pncn niatic gin, but whether the gin is a pneumatic or a brush gin is quite immaterial to my present invention. In Figure 1 T have a so indicated a feeder mechanism, 6, at the exit opening, 7, of which, my new chute is mounted.

My new chute is made up of a hood, (I, and a chute proper, Z), pivoted at b to the sides, a, of hood a. In the outer ed es of the ends, 6, of chute, b, are notches and at the lower end of chute, Z), a flap, 0, is carried, connected to the chute by slot 6 in Serial No. 553,514.

the ends I) of the chute and pins r in the ends (2' of the flap. l he slots Z) ha e at their upper ends retaining notches 72 The hood, a, is secured to the feeder casing 8 and, is preferably hinged, as at 8". A sec tion (4 hinged at a is provided and the lower edge of section a is inturned to form a detent rib a At either end of section a springs a are connected to the lower edge of hood-section a and extend out-side the side a of hood a, to'the rear edge of which they are connected under tension.

.t will now be obvious that by lifting outwardly hood section (6 against the resistance of springs a the chute Z) may be swung up ward on its pivots b and, the section a being released, the detent a will enter notches 72 and lock the chute in elevated position. It will also be obvious that, when it is desired to temporarily close the lower end of chute b, the flap 0 may be turned upward on its pivots 0 and lifted upward, until the pivots c travelling in the slots 5 reach the retaining notches 5 in which ituation the flap will be retained until it is released and restored to its normal position (see Figure 4),

When it is desired to temporarily stop the delivery of seed cotton to the gin, the flap c is turned upward across the exit of the chute and hangs by its pivots c in notches b of slots 6 Any of these adjustments may be made rapidly and without any special attention, the simple means employed being self-adjusting. At all positions of the flap 0, the surface of the bottom and sides of the flap are in contact with the bottom of chute b and with its sides 7), so that at no time is an opening formed between. the flap and the chute through which seed-cotton may escape.

The operation is as follows: Seed cotton is ejected -From the delivery opening 7 of the feeder 6 by the feeder drum into the hood, (I, of the chute, from which it passes by gravity to the chute proper, 7), and is by the chute directed to the desired opening of the gin. When it is desired to pass the cotton to the ginning roll box, the chute is adjusted as shown in Figure 1, full lines, to deliver into opening 1. When it is desired to direct the seed cotton to the huller roll lJlOX, the hood section is adjusted in its elevated position, as in dotted lines, Figure 1, to deliver to opening 4:. When it is desired to temporarily close the lower end of: the chute, the flap, c, is manuallylifted and is guided by the pin and slot connection to the notches 6 in Which it is suspended until manually released and restored to normal position I (see Figure 4) I claim:

- 1. A cotton chute, comprising a hood hav ing a hinged section, carrying a detent member; a spring, tending to draw the hinged section to; closed position; a pivoted chute carrying a detent-member to cooperate With the detent member on the hinged section.

2. Acotton chute comprising a hood having a hinged section carrying a detent member on its lower edge; a. spring tending to draw the hinged section to closed position; a chute pivoted to the hood ends havinga bottom and side Walls With a notch in the outer edge of its side Wall, to cooperate With the detent on the hinged section, all combined as described. i
